Several flexible and rigid analogs of 4H-1,2,4-triazoles (compounds 8a-g and 9a-g) bearing trimethoxyphenyl pharmacophoric unit, were designed and synthesized as potential anticancer agents. The in vitro cytotoxic assay indicated that both flexible and rigid analogs (8 and 9, respectively) can potentially inhibit the growth of cancerous cells (A549, MCF7, and SKOV3), with IC50 values less than 5.0 µM
设计并合成了带有三甲氧基苯基药效单元的4 H -1,2,4-三唑的几种柔性和刚性类似物(化合物8a-g和9a-g),并将其合成为潜在的抗癌药。体外细胞毒性试验表明,柔性和刚性类似物(分别为8和9)都可以潜在地抑制癌细胞(A549,MCF7和SKOV3)的生长,IC 50值小于5.0 µM。此外,作为化合物9的区域异构体的化合物10a-1显示出显着的细胞毒性活性,IC 50值为0.30至5.0μM。刚性类似物9a,10h和10k分别比依托泊苷对MCF7,SKOV3和A549细胞更有效。这些化合物对癌细胞显示出比正常细胞高的选择性,因为它们对L929细胞没有明显的细胞毒性。另外,代表性化合物9a和10h可以微摩尔水平抑制微管蛋白聚合。通过测定秋水仙碱-微管蛋白荧光的变化,表明化合物10h可与秋水仙碱口袋处的微管蛋白结合。分子对接研究进一步证实了有前途的化合物9a,10h和10k的抑制活性 通过
